Tom, Dick, Harry and the Gorilla
Harry eats one of the nuts when he gets
the bag and then shares the rest equally
with the Gorilla.
If the Gorilla got 17 nuts in total,
how many nuts were
originally in the bag?
Solution:- Tom, Dick, Harry and the Gorilla
Let x be the number of nuts in the bag originally.
Tom gets ½(x-1) of the nuts. Dick gets ¼(x-1).Harry gets and Hilda gets
Solving the equation , gives x = 129 nuts in the bag.
Therefore Tom = 64 nutsDick = 32 nutsHarry= 16 nutsHilda = 17 nuts
